This study aims to investigate the color characteristics of female fitnesswear by analyzing the status of color usage and color arrangement method of each item of female fitnesswear of sports brands. This study targeted eight global total sportswear brands. A total of 2956 colors of female sportswear were collected and analyzed from the homepage of each brand. As a result of analyzing the color of fitnesswear, first, the overall color of the fitnesswear showed high distribution centered on PB, Bk and R of low color tone, such as p and dkg. Moreover, bright tone colors were added for vitality and functional image of sports. Second, as a result of analyzing the color of each item, commonly, the PB, Bk and R had large proportions. Third, as a result of analyzing 2-color arrangements of fitnesswear, color arrangements including achromatic color had overwhelmingly higher frequency than color arrangements that had only chromatic colors. This shows that the color arrangement using achromatic color is important and has a higher preference. Fourth, as a result of extracting the representative color arrangement as color chip and comparing, the 2-color arrangement of female fitnesswear had the characteristics of the color arrangement of large area main color and small amounts of emphasized color centered on achromatic colors of Bk and W. This study is meaningful that it can be utilized as basic data for color planning of fitnesswear brands by subdividing female fitnesswear into 4 items and analyzing the color-tone and arrangement.

지역적인 영상의 색변환이란 영상에서 특정 색을 포함하는 영역을 추정하고 이를 원하는 색으로 변환시키는 것이다. 기존방법에서는 색차만을 이용해서 바꾸고자 하는 색을 포함하는 영역을 추정하고 이를 변환하였다. 따라서 변환되는 색 주변에서 원하지 않는 색결점(color artifact)이 나타나게 되었다. 제안한 방법에서는 이러한 색결점을 줄이기 위해 컬러 카테고리 맵과 수정된 color influence map을 결합한 지역적인 색변환 방법을 제안하였다. 컬러 카테고리 맵은 모든 색을 사람의 인지를 기반으로 11가지의 컬러 카테고리로 나눈 것으로서, 컬러 정보만을 이용해서 먼저 바꾸고자하는 색을 포함한 입력 영상의 지역 영역을 대략적으로 추정한다. 다음으로, 수정된 color influence map을 이용하여 인접한 영역의 색을 고려한 색변환 정도를 계산한다. 기존의 방법처럼 단순히 동일한 가중치를 주는 색차보다는 밝기와 색도에 서로 다른 가중치를 주어 수정된 color influence map을 계산하였다. 마지막으로 각각의 컬러 카테고리 맵과 수정된 color influence map에 가중치를 결합하여 지역적인 영상의 색변환을 수행하였다. 실험을 통해 제안한 방법과 기존의 색변환 방법의 결과 영상을 비교해 보았으며, 제안한 방법에서 색결점이 적게 나타나는 것을 확인할 수 있다.

Public uniforms play an important role in creating the color and image of urban environment beyond the level of simple working clothes for unity and practicality. Hence this study aims to compare and analyze the color characteristics and images of the police officer, fire fighter, and street cleaner uniforms at home and abroad to guarantee the wearer's safety, increase convenience and agreeability, and give emotional satisfaction to citizens in harmony with urban environment color as public uniforms. For study methods, literature review investigated urban environment, color, and uniforms as public design. Empirical study extracted color data from the public worker uniforms of the world's top 20 cities selected by 'Newsweek' in 2010 and analyzed their colors, tones, and color images. The results of this study are as follows. The most common color for police uniforms were PB(dk) as the main color, PB(p) as the sub color, and Wh as the accent color. For fire fighter uniforms, PB(dkg) was the most common main color; GY(v), as the sub color; and ItGy, as the accent color. The most common color for street cleaner uniforms was YR(v) as the main color; GY(v), as the sub color; and mGy, as the accent color. As a result of analyzing color images of these uniforms, it was found that police uniforms commonly used a modern image; fire fighter uniforms commonly used a natural image and a cool casual image; and street cleaner uniforms commonly used a casual image. As examined above, the color of public uniforms suitable for urban environment and job characteristics is very important to establish the image of public institutions, as well as to create an urban image.

The purpose of this study is to analyze and compare the color characteristics of preferred summer clothing textiles, such as shirts, blouse, slacks and skirt. 109 male and female college students evaluated the preference to clothing textiles in previous research and top 10 kinds of textiles were chosen for each clothing item. To analyze the color characteristics of preferred textiles, spectral data were measured with spectrophotometer. By the results, color and color tone, value of L, a, b according to clothing item and season were compared. Chromaticity diagram was drawn, too. The results of this study are as following: 1. Color characteristics of shirts textile college student preferred for summer was PB color and p tone. The textile, in general, represented simple color that is close to achromatic color with light and soft shade. 2. The most preferred color of blouse textiles was G color and It, d tone. The color characteristics of blouse textiles represented stronger and more brilliant than those of shirts. 3. For slacks, colors of preferred summer textiles were mostly B, YR color and p, It.g, dk tone. Therefore, preferred textiles for slacks represented simple bluish or brownish color that is close to achromatic color with light or dark shade. 4. The most preferred color of skirt textiles were Y, R color and It tone. Skirt textiles had various colors compared to slacks. 5. College students generally prefer simple cold color that is close to achromatic color, because shirts and slacks have high frequency of wearing. In color tone, light and soft tone were preferred for shirts, and for slacks, they preferred light or dark tone. Comparatively, blouse and skirt which have low frequency of wearing represented various colors which contain more brilliant and stronger toned warm colors. 6. By the result of analyzing L, a, b value, shirts and blouse textiles showed higher L value than those of slacks and skirt. The textiles preferred by college students were generally close to achromatic color, because values of a, b were very low. This was confirmed with the result of chromaticity diagram. 7. In pattern of preferred textiles, solid textile were preferred mostly for shirt, blouse, skirt and slacks, and stripe pattern was preferred secondly.

The research Interest of this paper is focused on the efficient clustering task for an arbitrary color data. In order to tackle this problem, we have tiled to model the inherent uncertainty and vagueness of color data using fuzzy color model. By laking a fuzzy approach to color modeling, we could make a soft decision for the vague regions between neighboring colors. The proposed fuzzy color model defined a three dimensional fuzzy color ball and color membership computation method with the two inter-color distance measures. With the fuzzy color model, we developed a new fuzzy clustering algorithm for an efficient partition of color data. Each fuzzy cluster set has a cluster prototype which is represented by fuzzy color centroid.

In this paper we focused on the color representation prob1em based on fuzzy set theory. The main factor is the determination or computation of color membership function and color difference formula. The mathematical formula to calculate the color difference should generate a uniform color scaling, and due to this reason we adopted a CIELAB color- space as a fundamental feature space. With the help of the CIELAB color space we created a new color model, referred to fuzzy color model, which can represent the ambiguous characteristics underlying colors. Based on the proposed color difference formula between fuzzy colors, we could obtain the membership computation method of an arbitrary color for a given color family.

In case of outputting the image with color printer, image is occurred color distortion by characteristics of paper, effect by overlap between neighbor dots and the mechanical characteristics if printer. Color calibration is needed to reduce this color distrotion. To color calibration, we select the color sample in printer color gamut. The accuracy of color calibration is determined by the number of sample, distribution, and calibration method. Generally, color space is selected the color sample dividing equal interval. In this case, the range of gamut of printed color patches is reduced due to the effect of inks overlap. Therefore, error is occurred when color transformation relatively. In this paper, we have the color sampling based on equi-visual perception and then reproduce the color using the Neural-Network and interpolation by LUT.

In this paper, we propose a favorite color correction algorithm for color enhancement in color application system which represent preferred colors for viewer's demands. The proposed algorithm corrects skin color which is widely used as a reference color for color control of color application system, blue color which is directly related to tri-stimulus values, and green color which has higher visual sensitivity. In the proposed algorithm, the vaiation range of phase detector output voltage was minimized for the favorite color saturation changes, thus the favorite from the burst signal for the phase detector characteristic, thus the favorite color was easilty detected from the other color without overlapping of correctionranges.
